Power Up
Power Up
The front LED indicators and configuration switches are illustrated in
Figure 4 . On power-up the green PWR LED should light and the yellow
CONF LED should illuminate for the duration of module initialization.
Operation Indicator LEDs
With factory default configuration and a valid input signal connected, the
green PWR LED, and one of the yellow signal standard LEDs (525 or 625)
should illuminate (refer to
Table 2 on page 12 to see the possible operating
indicator combinations).
Video input presence is indicated by an illuminated VID PRES LED and the
appropriate 525 or 625 LED. The 525 or 625 LED will illuminate to indicate
detection of a 525-line or 625-line input signal. The VID PRES LED indi-
cates the presence of valid composite sync on the Y/G channel or reference
input.
